Application filed July 28, 1919.

' To all whom it may concern:

Be it known that I, LORENZ ERTL, a citizen oi the United States, residing at Ivanhoe, in the county of Lincoln and State of Minnesota, have invented new and useful. Improvements in Operating- Tables, of which the following is a specification.

This invention relates to an operating table, and more especially to a table designed for use in connection with the operation of ringing and castrating boars, and other animals.

The objects of the invention will appear from the following description, taken in connection with the accompanying drawings.

In the drawings,

Figure 1 shows the device in side elevation,

Fig. 2 is also a side elevation, with the side boards open,

Fig. 3 is a top plan view Fig. 4- is a section on line 4-4. of Fig. 1,

Fig. 5 is a fragmentary view in section, 0t an adjustable element,

Fig. 6 is a vertical transverse section of the main portion of the struc ure.

The top oi the table is designated 10, the attcr being mounted on legs 1:2 retained in holding or clamping devices, of novel constrnction, and referred to below. The front board is designated 1% and is provided with an aperture 15 the board being hingedly connected at 16 with the end of the top 10.

Braces 17 support the front 'l'woard.

The side boards are designated 18 and 19 and are hingedly connected with the top 10, these side boards being thrown to vertical position, or to horizontal position, according to circumstances. Flexible retaining devices or chains 21 hold the side boards in an inclined position, when desired, this position being most convenient when an adult animal is being operated upon. The boards are placed in vertical position, that is, are closed, when a young animal, say from three to four months old, is being operated upon.

A11 elevating or raising board 23 is hingedly and adjustably connected at'24 with the top 10 and is supported by means of an adjustable device 25, in the required position, the angle of inclination being varied Specification of Letters Patent.

Serial No. 313,677.

neath one end of the table 10, is designated 30. I

Each of the legs 12 is mounted in a hold ing oevice designated 32 and connected with the underside of the top element 10, this leg holding device being oiiset from one element of the hinge 35, the other element of the hinge being provided with an ofiset 33 constituting a stop or rest, for retaining the side board or side boards in position, when lowered.

Securing devices or ropes 35 may be passed through apertures 36, 36 in the side boards, for securing the animal, and especially the legs thereof. The ropes may also engage devices 39 and be secured by winding around elements 40.

The leg holding devices 28 may be in the form of angle brackets having ropes 29 connected therewith. The front and side boards may be reinforced with iron where desirable.

What I claim is 1. In a device of the class described, a top, legs for supporting the top, side boards hingedly mounted, a front board, flexible devices retaining the side boards in an adjusted position, an adjustably mounted clevating device connected with the top inter? mediate of the ends thereof, means carried by the side boards for limiting the outward movement thereof and devices positioned to beengaged by said means and constituting leg supports.

In a. device of the class described, a top, 7

a plurality of side boards movable out' LORENZ ERTL.
